Movie Plot: Inspired by the true story known as the Mekong Massacre–two Chinese commercial vessels are ambushed while traveling down the Mekong River in the waters of the Golden Triangle, one of the largest drug-manufacturing regions in the world. 13 sailors are executed at gunpoint, and 900,000 methamphetamine pills are recovered at the scene. Upon discovery, the Chinese government immediately sends a band of elite narcotics officers led by Captain Gao Gang (Zhang Hanyu) to the Golden Triangle to uncover the truth behind the murders. Tea field owner and Golden Triangle-based intelligence officer Fang Xinwu (Eddie Peng) joins the investigation.
